attaching panniers to Carbon frame

clarkey cat

is this like a really big no no?
or really not a problem.

would need to get the relevant fixtures.

Cheers.

erm...id say no no?

if you haven't already got mounting points (forgot their proper name) you will have to use them screw on things which crush to tighten on

i wouldn't risk it my self, i think you need a new bike

I don't think they make anything to attach panniers direct to the frame. You will need a rack to attach the panniers to

Panniers make carbon melt, don't you know anyfink?

I believe you can get racks that mount to the axle - which will make a rear puncture more of a PITA, but will mean the stress is on steel not carbon. Don't see why it shouldn't work.

Carbon frames are not necessarily strong in all axis at each frame component. So, I would be a bit careful about mounting panniers and the weight in said panniers. The weight will still pull away from the frame at the highest point of the fitting, no matter how well braced at the lowest point of fitting....gravity eh!

Some frames are only strong with the weight on the top of the frame - weight distributes through the top tube, head tube, forks and down the seat tube and seat stays - i.e. they are strong under downward pressure, however any forces from the side of the frame could damage the frame as it is not designed to be strong in that direction.

So, I would look at the various types of pannier/rack fitting and where the top mount of the pannier clips on.

I would rather not chance it myself, as frame repair may not be possible and the consequences of frame failure are fairly horrible on both individual and bank account.

N+1 - Get a "cheap" bike with mounts for rack and panniers for carrying the heavy stuff and use a good back pack on the carbon bike for everyday use.....

I really don't see any problem at all with drilling holes in the chain-stays, seat-stays and seat tube to accommodate a rack or panniers. Use a ¼" drill (or larger) to make it easier to get the screws lined up, and some big washers to spread the load. Do the bolts up really tight as well to keep everything in place - carbon responds well to compressional forces, probably.

If - err - when it works and the pannier is in place, carry on drilling to create a futuristic honeycomb frame that weighs less than the air it displaces. Bingo - the impossible triumvirate of light, strong, and cheap - worthless indeed - and as a bonus you'll be the talk of the town.

There is literally no downside to doing this*, and the weight gain from the pannier holes could easily outweigh the weight of the rack. Easily.

* None. Although drilling holes will affect the strength, safety and resale value of your bike. The value of your bike full of home-made holes may go down or downer and you'll probably die riding it. Please consult an independent specialist before doing anything completely chuffing stupid.

Carbon drillium..... :shock:

Now your talking!

touring or just carrying more cake to work?

if the later, consider a carradice

Here is a better picture:

Probably close to the limits of the 1970's drillium craze;

Just looking at options as I like to mix things up. I do actually own one of these so I could get a seat-post mounted rack but then I'm guessing similar issues apply to all the points above and I'd need to get an alloy (or titanium) seatpost.



N+1 is obviously the ideal. I just dont have space. Basically I miss owning an audax bike. I moved over to Carbon because I had an itch that needed scratching and now I want to go back.

My Wilier ain't full carbon but does have carbon seat stays, so when I did a long ride I used a seatpost-mounted rack. The seatpost is Alu, as is the rest of the frame.

The bike didn't disintegrate, nor did it dissolve in the relentless Cornish rain. All-carbon frames may be more soluble though.

Big back pack!

if your carbon bike is a Look 586 SL with full DA kit, then I will swap you for my old Aende Columbus Record Steel with 14 speed 105.

I think it's a fair deal considering your disposition..... :shock:

I've got a seatpost mounting pannier rack kicking about in the garage if you want ot give it a go. Stop by on your way home one evening.

Shimano?

I dont think so. Thanks anyway.

Cheers V. I'm going to see what storage facilities I have at my new place of work so hopefully I can get away with just pockets as I believe they cater really well for cyclists but if not I'll give you a shout.

All of this is just treating the symptoms though... I miss riding steel.

Why? Although I'd have reservations about attaching P-clips to a carbon seat tube, a carbon seatpost will be fine; it's specifically designed to handle clamping forces, aswell as various off-axis loads from you moving your weight around on the saddle. I'm looking at a lightweight carbon seatpost on my desk right now, and the walls are a good 1/8" thick (frame tubes on a decent carbon bike will be a fraction of this).

I believe you can get racks which will attach to your quick release and seatpost. The Q/R attachment is obviously a pain if you want to the the wheel out, but apart from that I can't see a problem. In particular, the load on the seatpost in this configuration is negligible, all the weight is transferred straight to the wheel.

clarkey cat

Ah yes. Miss that too.

Have you finished with it by the way? If so, I'll have it back cheers.

veronese68

Yes thanks. I'll give it a quick wipe before I return it.

you can get seat post clamps which have two bolt holes to take a standard rack mount to avoid p clamps and to avoid clamping anything to a carbon seat post.

Although you've still clamped the frame onto your water-soluble carbon seat post...
